Instructions
Materi : Variable & Data Type
1. Save the result of (42 - 11) * 22 to result.
Print result.2. Store the value 15 in a variable named a_value.
Store the result of (25 - 7) * 17 to a variable named a_result.Using the print() command, display the following:
The value stored in the a_value variable.
The result of adding 12 to the variable a_result.
The result of adding a_value to a_result.
3. In the code editor on the right, we attempted to store 34000 in a
variable named old-income, and 40000 in a variable named new income. But
both of these variable names cause syntax errors, so we commented-out
the code.
Change the variable name old-income to old_income to prevent a syntax error.
Change the variable name new income to new_income to prevent a syntax error.
Remove the # from each line so that the code will run, then run the code.
4. Update the variable income by adding 6000 to its current value.
The variable income is already shown in the code editor on the right.Print income.
5. Assign a value of 20 to a variable named variable_1.
Assign a value of 20 to a variable named variable_2.Update the value of variable_2 by adding 10 to its current value. You can take advantage of the += operator.
Update the value of variable_1 by multiplying its current value by 4. You can take advantage of the *= operator.
Display variable_1 and variable_2 using print().
Assign the float 2.5 to a variable named variable_2.
Update the value of variable_1 by adding the float 6.5 to its current value. You can use the += operator.
Update the value of variable_2 by multiplying its current value by the integer 2. You can use the *= operator.
Display variable_1 and variable_2 using print().
Assign the value 2.8 to a variable named variable_b.
Round variable_a using the round() command, and assign back the rounded value to variable_a.
Convert variable_b from a float to an integer using the int() command, and assign back the converted value to variable_b.
Display variable_a and variable_b using the print() command.
Assign the string 4.0 to a variable named average_rating. Make sure you don't mistake a string for a float.
Assign the string 1724546 to a variable named total_ratings. Make sure you don't mistake a string for an integer.
Assign the string free to a variable named price.
Display the app_name variable using print().
9. Assign the string Facebook's new motto is "move fast with stable infra." to a variable named motto.
Notice there's a . character at the end of Facebook's new motto is "move
fast with stable infra." — you'll need to include the . character in
your answer.Display the variable motto using print() — displaying motto is required for answer checking.
Assign the float 3.5 to a variable named fb_rating.
Convert fb_rating from a float to a string using the str() command, and assign the converted value to a new variable named fb_rating_str.
Concatenate the strings stored in facebook and fb_rating_str to form the string Facebook's rating is 3.5.
Assign the concatenated string to a variable named fb.
You'll need to add a space character between Facebook's rating is and 3.5 to avoid ending up with the string Facebook's rating is3.5.
Display the fb variable using print() — this is required for answer checking.
